Abstract
THE genus Gunnera (Haloragaceae) contains forty species, all herbaceous, ten being endemic to New Zealand. Glands occurring at the bases of leaves become invaded by the blue-green alga Nostoc puntiforme1,2 which becomes intracellular3 and is capable of nitrogen fixation in culture2,4. Algal glands have been described for several New Zealand species5,6.
